what did the president have AT THE G-20 DINNER WITH THE CHINESE?

BEEEEP.,,, Wrong answer. It was crow.

I used a tool called an Internet search engine to find out. The one I used is called Google, but there are others around. I used the search engine parameters "g20 dinner menu."

The second hit on the search engine's results seemed to be relevant.

First course: salad
Second course: sirloin
Dessert course: pancakes

For more detail, please feel free to use the Internet search engine of your choice.

Enjoy!
